Extend C-DEREF guideline to say smart pointers should always be transparent in Debug representation

7

The canonical Debug implementation for **any** type that implements Deref is: ```rust Debug::fmt(&**self, formatter) ``` This principle came up during libs team discussion of https://github.com/rust-lang/rust/pull/48553.

Type macros may follow a different naming convention

https://github.com/rust-lang-nursery/api-guidelines/issues/135#issuecomment-343698387 suggests a nice one: > I've been using `PascalCase!` for macros that expand into types. (e.g. `Array![i32; 5; 4; 3]` which expands into `[[[i32; 3]; 4]; 5]`) I did...

https://github.com/rust-lang/rfcs/pull/1860#issuecomment-279848322 gives an interesting reason to consider not following the C-SMART-PTR guideline. In that case we decided to follow the guideline anyway, even though the motivation for the guideline does...

Add an appendix with links to the open "soliciting opinions" issues

Along with a summary of the discussion and perspectives so far for each.

For example clicking on the "Macro syntax is evocative of the output" currently links to https://rust-lang-nursery.github.io/api-guidelines/macros.html#input-syntax-is-evocative-of-the-output-c-evocative. Instead it should link to https://rust-lang-nursery.github.io/api-guidelines/macros.html#c-evocative as the checklist does. This would allow us...

### What does this PR try to resolve? As flagged in https://github.com/rust-lang/cargo/pull/10079#issuecomment-1170940132, it's not great to assume that git SHAs would always be 40-character hex strings. In the future they...

# Meeting proposal info - **Title:** Standard library implementation ownership - **Type:** non-technical # Summary I am interested in whether it would make sense for the compiler team (or subteam...

Macos builds are failing

Overnight all three of our nightly, beta, and stable macos builds began failing with: ```console thread 'test' panicked at 'assertion failed: `(left == right)` left: `""`, right: `"target/debug/examples/print\na\nb\nc\n"`', tests/test.rs:19:5 ```

For example, avoid expanding `try!` and other macros inside the output of proc macros. cc @djc
